5,523 PointsI wrote it two ways, both work
ul.insertBefore(nextLi, li);
that line can be replaced with:
li.after(nextLi, li);
i understand the first one just reverses the up button but can someone explain what the second version is doing?

231,236 PointsThe "after" method is another way to add an element to the DOM; but as you apparently noticed already, it's applied to a sibling instead of a parent.
Also, according to the MDN page, this method is classified as experimental, so it would not be recommended for use in production code.
